Description of the project:

John Shannon of Roberts & Partners comments: "The system effectively achieves total heat distribution around the racking and working areas of the building. Reznor warm air units are renowned for good quality and longevity - I had no hesitation in specifying them for this application."

Norwich Union, the UK’s largest insurance group, extended its storage capability with the acquisition of a new facility in Norwich. The building required a completely new heating system to ensure a comfortable working environment for employees could be maintained at all times.

As Norwich Union’s main storage facility, the premises contain floor-to-ceiling racking, with aisles to allow fork-lift retrieval of documents.

Ensuring even distribution of heat around the building, with its racking, mezzanine floor and high bays, was a key criterion of the heating systems.

Eleven Reznor C4074 compact warm air unit heaters were wall-mounted between the racks, just below roof level. Strategic positioning of the heaters around the perimeter of the building ensure warm air discharges directly down aisles between racks. The warm air is redistributed throughout the main storage and high bay areas by 20 roof-mounted Maximizor recirculation fans.

In addition, a ducted warm air system powered by five Euro T2236 units was installed at mezzanine floor level.

Despite the considerable challenges posed by the interior architecture, the Reznor heating system maintains a constant 21°C throughout the building, thanks to the correct positioning of heaters and the addition of a ducted system to the mezzanine floor. Employees feel comfortable wherever they are working within the premises.

The Reznor system was recommended by Roberts & Partners of Glasgow, retained consultants for Norwich Union, as they believe Reznor to be renowned for their high quality systems, and was then installed by M & E contractor ABB Building Technologies Ltd of Ipswich.
